Dapagliflozin (Oral route)
Sodium Glucose Co-Transporter 2 Inhibitor
Uses of This Medicine:
Dapagliflozin is used together with proper diet and exercise to treat type 2 diabetes. It works in the kidneys to prevent absorption of glucose (blood sugar). This helps lower the blood sugar level. Dapagliflozin does not help patients who have insulin-dependent or type 1 diabetes. Type 1 diabetic patients must use insulin injections.
This medicine is available only with your doctor's prescription.

Your doctor may give you insulin, fluid, and carbohydrate replacement to treat this condition. Tell your doctor right away if you have nausea, vomiting, trouble breathing, increased thirst or urination, or stomach pain.

This medicine may cause vaginal yeast infections in women and yeast infections of the penis in men. This is more common in patients who have a history of genital yeast infections or in men who are not circumcised. Women may have a vaginal discharge, itching, or odor.

Talk to your doctor about how to treat low blood sugar.
Hyperglycemia (high blood sugar) may occur if you do not take enough or skip a dose of your diabetes medicine, overeat or do not follow your diet plan, have a fever or infection, or do not exercise as much as usual.
